FLUID-DISPENSING DEVICE.

Application filed June 29,

T0 aZZ w from it may concern Be it known that I; It. Bsnnsnnnn, a citizen of the United States of America, and a resident of Greenwood, in the county of Greenwood and State of South Carolina, have invented a new and useful Fluid-Dispensing Device, of which the following is a specification.

My invention relates to improvements in containers for various kinds of fluid which it is desired to dispense periodically in small quantities, such as mucilage, water, or other material in a liquid or fluid state, and consists essentially of a container or receptacle of any suitable shape and size, and a closure for such receptacle, which closure has a top extension in which there are fluid and air perforations, all as hereinafter set forth.

As is well known, much difliculty is experienced in dispensing and applying small quantities of mucilage or other viscid material, owing to the fact that the same does not flow freely, on the one hand, or else it flows too freely, on the other hand, except under the proper conditions in either case; the same is generally true with regard to the dispensing of water for the purpose of moistening postage stamps, envelope flaps, and the like. The primary object of my invention is, therefore, to provide a dispenser for mucilage, water, or other fluid material, with comparatively inexpensive and simple means whereby the above-mentioned difficulties are remedied, overcome, or alleviated.

and the contents of said dispenser can be used to best advantage and with the greatest facility.

Other objects and advantages will appear in the course of the following description.

I attain the objects and secure the advantages of my invention by the means illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a fluid-dispensing device which embodies a practical form of my invention; Fig. 2, a side elevation of said device, with the cap in central, vertical section; Fig. 3, a top plan of said cap, and, Fig. 4: a side elevation of the cap taken at right-angles to the position of the cap as it appears in the other views.

Similar reference characters designate similar parts throughout the several views.

In the drawings, a container or receptacle is re resents at 1, a can therefor a 1921. Serial No. 431,323.

The receptacle 1 may be of any convenient shape and size, and has a neck 3 which is provided with external screw-threads The flange of the cap 2 is provided with internal. screw-threads 5 to engage the screw-threads 4. Thus it is seen that the cap 2 may be screwed on and off of the neck 8, a provision that is necessary or at least desirable, in order to facilitate closing the receptacle 1 after the same has been filled, and to enable said receptacle to be refilled when refilling is a requirement. Screw-threaded connections between containers and their caps being old, I do not seek to claim the same per se.

Preferably the receptacle 1 is made of glass and the cap 2 is formed out of sheet-metal, and in such event the screw threads 4- and 5 are respectively moulded on the neck 3 and rolled into the flange of said cap, in the customary manner.

The new features of the dispenser reside in a hollow, raised portion or extruded part of the top of the cap 2, such as that represented at 6, whereby a fluid and air chamber 7 of comparatively restricted area is formed in the upper portion of said cap. or constitute such upper portion. The ex truded part 6 has at least two openings, as 8, therein. Preferably the openings 8 are in the top of the part 6.

For reasons which are clearly apparent, the openings 8 should be smaller in the top of the dispensing chamber 7 for a recepatcle l for water or other thin fluid, than they are in the top of the dispensing chamber 7 for a receptacle which contains mucilage or other thick or vise-id material.

When the device contains mucilage the latter is dispensed by holding the device so that one of the openings 8 is above the'other of said openings, and tilting said device to cause the mucilage to flow into the chamber 7 and out through the lower opening 8 onto the place where it is desired to deposit the same. At this time air passes through the upper opening 8 into the chamber 7, and into whatever space there may be above the mucilage, in the neck 3 and the receptacle 1, to relieve the partial vacuum that otherwise would be formed and interfere with, ifnot completely check, the flow of the mucilag'e from the container. The extrudedpart 6, as here shown and by. preference, is oblong in plan and has sites whiclriserve fro-tnthe top of Cir cap 2 upwardly or outwardly and inwardly or toward each other. By giving this form to the part 6 in which the chamber '7 is located, an exterior project-ion or rib or ridge is produced which lends itself especially well to the act of s neading the mucilage after the same has escaped from said chamber and been deposited. l do not, however, desire to be unduly restricted with regard to the shape of the part 6.

In the event it be desired to obtain more than one or two drops of mucilage. or if it be desired to produce a constant How, the container, is placed in an approximately horizontal position, with the openings 8 in approximately the same vertical plane, when the mucilage will escape in a small stream through the lower opening 8, provided, of course, that the upper surface of the mucilago in the container as now positioned be below the upper opening 8. This is an important advantage in some cases.

lVater, may be dispensed from the device, either in drops or a small stream. in sub stantially the same manner as that described. above with reference to mucilage. And here, again, the part or ridge 6 becomes useful as a medium for spreading the water over the surface of a stamp or other object coated with adhesive material and upon which the water has been deposited,

The chamber '1" being of less area in plan. than the top of the cap 2,. aifords space only for a comparatively small portion ofthe contents of the receptacle 1., while the great mass of such contents is held back, when the device is placed in dispensing position, and it is from such comparatively small portion in said chamber that the actual discharge or flow takes place. In consequence of these conditions the dispensing process is rendered more flexible, a it were. and kept under better control, than would be the case if the openings 9 were in the flat top of the cap. In other words. the presence of the chamber 7 materially increases the facility with. which the dispensoperation is or may be controlled. It also provides a space for the air which enters through the upper opening 8, when the device is in use, which space is more suite able for this purpose than would be the case if the chamber 7 were omitted:

Among the varied uses, for which this fluid-dispensing device is adapted, is that of moistening the finger,when the receptacle contains water, for the purpose of assisting in counting paper money and papers. This is effected by closing with a finger one of the openings 8, placing the finger to be moistened over the other opening 8. and tilting the device to permit a drop or two of water to come into contact with said lastnamed finger.

I amaware that various kinds and types of fluid or liquid dispensers have been protop portion, which part has a top that is flat throughout its entire. area, and provided with fluid and air holes.

2. As an improved article of manufacture, a fluid-dispensing cap, for a fluid-dispensing device, comprising flange and top portions, said flange portion being screwthreaded, and an extruded hollow part on said top portion, which partis of greater dimension in one direction than in the other, and has a top that is flat throughout its entire area, and provided with fluid and air holes.

8. As an improved article of manufacture, a fluid-dispensing cap, for a fluid-dispensingdevice, consisting of flange and top portions, said flange portion being screwthreaded, and an extruded hollow rectangular part on said top portion, which part has sloping sides, and a top that is flat throughout its entire area, and provided with fluid and air openings.
